Question:

In writing a fantasy story, how would your character go about killing a dragon?

Original answers only please. Remember a dragon is HUGE, breaths fire, flies, is coated in thick scales and is very intelligent. Clue - charging up on a stead with a lance isn't gonna do it!

Best Answer - Chosen by Asker: My secret weapon for taming a dragon is the beautiful purple dragon that all the guy dragons can't resist.
She is able to have them woo her, until there is absolutely nothing else they can concentrate on except getting a little tail off my female dragon.
Once they've got it on.
He's in the palm of my hand, since he doesn't want to do anything but stay on the female dragon's good side.

Then a few years later we have all sorts of little baby dragon's and they all live happily ever after.

My goal isn't to kill the dragon, but to re-establish their species!!!
